   - After `shutdown`, `LogProcessor` will not process any new logs
 - Moving LogRecord implementation to the SDK. [1702](https://github.com/open-telemetry/opentelemetry-rust/pull/1702).
     - Relocated `LogRecord` struct to SDK, as an implementation for the trait in the API.
+- **Breaking** [#1729](https://github.com/open-telemetry/opentelemetry-rust/pull/1729)
+  - Update the return type of `TracerProvider.span_processors()` from `&Vec<Box<dyn SpanProcessor>>` to `&[Box<dyn SpanProcessor>]`.
+  - Update the return type of `LoggerProvider.log_processors()` from `&Vec<Box<dyn LogProcessor>>` to `&[Box<dyn LogProcessor>]`.
